TOPIC: One Way Privacy Film

Looks good Colin. For the information of others who may be following this thread, I installed external total mirror film on my large angled front windows at the beginning of this season. The result achieved is a very very significant reduction in heat transmission whilst allowing completely adequate vision from the inside for safe helming.
Bottom line, - am very pleased and am seriously considering applying it to other wheelhouse windows, but will wait to see how it fairs after a winter.

Thanks. Got a few bronze and silver internal samples from The Window Film Company and Window Films Direx and stuck them up at home. None the wiser!! A silver film from Window Films Direx looks more bronze from the outside than the bronze films do!!
Spoke to suppliers and they acknowledged that DGUs can explode - units have to have toughened glass inside and out.
Logically, external seems to be the way to go. Even with a fully toughened DGU, the heat stress can't be good for the sealing leading to failure and moisture inside the DGU - which has happened to 3 of 4 saloon DGUs.

I've just applied an outside 99% film. So far it's not been hot enough to know if it is effective enough in it's heat reduction, and I have concerns about how it will weather overwinter. But only time will tell. I could have gone for an internal film but considered that I wanted the glass to remain as cool as possible and by putting the 'mirror' on the inside the heat would go through the glass twice and be heated twice as much. Not cheap though....

Hi Colin
From the outside, silver ish, From the inside, almost colourless.
We did, salon, galley and cabins and "dog box", basically everything except the wheel house, and I have thought of that, many of the 110 metre grain barges on the Saone / Rhone have it, and I don't see the Brigade Fluvial jumping all over it, as said, almost 100% vision from the inside.
Never knew there were different colours, worth looking into. It is easily applied and (nearly) as easy to remove. As with most things Cleanliness is next to Godliness when putting it on, and keeping everything lubricated with a drop of washing up liquid in a spray bottle of water.
Yes on the inside, but be careful, an office building that I worked in was treated, to stop solar gain, the heat was "Bounced" back into the gap between the two panes of the double glazing, and "blew" quite a lot of units on the south facing side of the building. Might be worth investigating if this effect has been sorted out now. At the time the only solution was to remove the film and apply an "outside" grade.

Thanks Ian and Paul.
The film is for the saloon windows which are double glazed units in a teak frame.
I assume the Lidl film was a basic silver colour and now found lots of colours - such a choice! I quite like the idea of bronze - might be a better match for the woodwork.
I also assume the film is on the inside of the glass.
Time to get a sample or 2.

Hi Colin
The film comes in different grades as I'm sure you have found.
From memory we installed 70%.
Results.
Immediate reduction of solar gain from radiated sun light - much cooler.
Wildlife watching - Fantastic, the Kingfisher is 60cm away and cannot see you moving so carries on fishing - wonderful.
Privacy - complete - good for spying on the neighbours :-)
The view out is hardly compromised, just a reduction in glare.
Brought from Lidl six or seven years ago. Savings by buying from Lidl means you can buy a Satellite Finder at the same time :-)
As said, lights on at night - don't do anything you do not want the world to see.
Fully recommended.

We have fitted a reflective one way privacy film - very effective but you do get young girls pouting and doing their hair in the reflection, also bear in mind that a night and with internal lights on the privacy is reversed!!

Wondered if anyone had used one way privacy film?
Seem to be a variety of colours available.
Only difficulty I can see is not being able to look in through the window to see the TV screen for satellite signal strength!
